Tamron 11-20mm f2.8 DI III-A RXD Lens for Canon RF-S Mount

The Tamron 11-20mm F/2.8 Di III-A2 RXD Lens is an ultra-wide-angle zoom designed for Canon RF-mount APS-C mirrorless cameras. Its constant f/2.8 maximum aperture offers excellent low-light performance and depth-of-field control, all in a compact, lightweight design. Ideal for landscapes, astrophotography, and architecture, the lens features an optical design with XLD, LD, and aspherical elements to minimize chromatic aberrations and color fringing, ensuring sharpness and color accuracy.

Tamron's BBAR coating reduces flare and ghosting, enhancing contrast in challenging lighting. The RXD stepping motor delivers fast, quiet autofocus suitable for stills and video. With a close focusing distance of 5.9" at the widest setting, the lens excels in wide-angle macro photography, creating striking perspectives that emphasize nearby subjects while making backgrounds appear smaller. The bright f/2.8 aperture enhances bokeh, adding a pleasing blur to backgrounds.

Constructed with moisture resistance and a fluorine coating, it handles harsh conditions while protecting against dust and smudges. A rounded seven-blade diaphragm further enhances smooth bokeh effects, making this lens versatile and robust for a range of creative applications.
